Initially I was looking at the Fieldpiece, but now I'm leaning toward the Testo because it's smaller and comes with a hard case.

What's your guys take on them? Or any other brand?

My -- I love the Testo line of test equipment and i am really happy with their products! If you are going to be working on alot of refrigeration and your in and out of freezers get the DIGI cools. If not then testo or Sman will do the trick. What ever of the three you choose you will be fine. JB and Yellow Jacket are over priced for their features.

If your not getting the results you desire then change. People change from either desperation or inspiration.

I've owned the testo, digocool 1600, and the sman3. The testo broke way too much. I can'tbelieve anyone has had a good experience with that piece of junk. The digicool seemed nice but the lead broke and it only read one line at a time.

The sman3 is by far the best. Watching subcool and superheat with precision is a wonderful thing.

Well, which one is easier to use? Has better features? More reliable? I kind of like the Testo because it looks smaller, fitting the hand better and it has a nice hard case. The Fieldpiece looks big. I don't want to be carrying something too big and bulky.

The fieldpiece has two temp probes which is important to me. I put them on once and don't have to switch back and forth. I use it for residential use so it is nice that 410a and r22 are 1 click away. The testo hook is cheap, the leads are like toothfloss, the screen cannot take a drop of water (voids the warranty), static discharge destroys the temp sensors according to the manufacturer. Look at the sman3 video...the thong is tough. The leads may eventually break but I will take them back if so.
